TDG was amongst the first globally to offer OLED lighting to the rail industry. With panels as thin as 0.2mm and as light as 4.0g this is an ideal solution for weight reduction and power savings within either a rail car or locomotive.

With output approaching 140 lm / W as well as a CRI greater than 90 (@4000k) and the ability to offer a fully flexible panel OLEDs are rapidly approaching the levels of efficiency of conventional LEDs with more flexibility.
